UNITED STATES PATENT GRINDING WHEEL DRESSER Carl 0. Klockars, Slatersville, n. I.

Application March 6, 1945, Serial No. 581,213

1 Claim. 1

This invention relates to a diamond holder, and more particularly to such a diamond holder adapted for use with diamonds adapted for dressing emery wheels on surface grinders, or the like.

A primary object of this invention is the provision of an improved diamond holder provided with means whereby the diamond, or diamonds, associated therewith may be adjusted both as to height, and as to angular inclination, with respect to an emery wheel or the like to be dressed, in such manner that various sizes and heights of wheels may be readily dressed with a minimum of effort, fatigue and time.

An additional object of this invention is the provision of such a diamond holder provided with means whereby the diamond or diamonds associated therewith may be readily positioned at any desired angle or height as desired.

A further object of the invention is the provision of such a device which will be sturdy and durable in construction, reliable and efiicient in operation, and relatively simple and inexpensive to manufacture, assemble, and utilize.

Other objects will in part be Obvious and in part be pointed out as the description of the invention proceeds, and shown in the accompanying drawings wherein there is disclosed a preferred embodiment of this inventive concept.

In the drawings:

Figure 1 is a side elevational view of one form of diamond holder embodying this inventive concept,

Figure 2 is an end elevational view of the device disclosed in Figure 1, and

Figure 3 is a top plan view of the device,

Similar reference characters refer to similar parts throughout the several views of the draw ings.

Having reference to the drawings, there is shown at ID a base plate, adapted to be positioned on a magnetic chuck I I, from which base a cylindrical post I2 extends upwardly a desired dis tance. A bracket, generally indicated at I3, including .a cylindrical bore I4 and bifurcations I5, is positioned about the post I2.

The bifurcations I5 are provided with aligned threaded apertures, through which is passed a bolt I6, provided with an ear or operating handle I1, the arrangement being such that movement of the handle I! serves to turn the bolt It to clamp the bifurcations I5, and the bore I 4 securely in any desired angular relation, or at any desired height upon the post I2.

The member I3 includes a depending portion 20, adapted to extend and overlie the base I0 and,

terminate at a point adjacent the chuck Il The portion 20 has a transversely extending bore 2| therethrough adapted to contain a diamond holder 22, the latter being held in position as by a set screw 23.

Extending outwardly from the depending portion 20 is a horizontal portion 24 provided with a vertical bore 25 adapted to contain a diamond holder 26, the latter being held in position as by a horizontally positioned set screw 21.

Thus it will be seen that the bracket I3 is provided with two diamond holders, one in a horizontal position, and the other in a vertical position, adapted to operate upon either the side or the face of an emery wheel, generally indicated at 30. From the foregoing, it will now be readily apparent that the angular relation of the bracket I3 .and hence that of either of the diamond holders 22 or 26 may be readily varied by movement of the handle I1, and consequent loosening of the bifurcations I5, permitting the bracket I3 to be readily rotated about the post I2. Correspondingly, it will be seen that a similar operation will permit the member I3 to be positioned at any desired height on the post I2 as desired, to accommodate any size or type of emery wheel as may be necessary.

Either or both diamond holders may, if desired, be provided with micrometer threads to permit precision adjustment, as when duplicate parts are being ground.

Now, from the foregoing, it will be seen that there is herein provided a device accomplishing all of the objects of this invention and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and. not in a limiting sense.

I claim:

A device of the character described including a base, a round post extending upwardly therefrom, an offset bracket having oppositely extending arms disposed in parallel relation and in different planes to each other, one of said arms being vertically bored and formed with bifurcated clamping portions connected therewith surrounding said post for vertical and circumferential adjustment with respect thereto, a threaded clamping bolt disposed through said bifurcated clamping portions, said vertically bored arm being transversely and vertically bored to respectively support a diamond holder and a locking UNITED STATES PATENTS set screw, and said other arm being vertically Number Name t and transversely bored to respectively support a 1 999 322 Enete 7 Apr 30 1935 diamon holder d a locking Set Screw dress 2:178:842 Paine Nov.
